Sunlight doesn't reaches this zone so no plants are able to grow.
no plants can grow in any zone but the sunlit zone
Plants need light to grow, in the abyssal/hadal zone, there is no light.
Close to the the marine's benthic zone, this zone is the bottom-most zone to the fresh water biome.
Sunlight can penetrate through the limnetic zone into the profundal zone.
Littoral Zone - In coastal environments and biomes, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. It always includes the intertidal zone and is often used to mean the same as the intertidal zone. However, the meaning of "littoral zone" can extend well beyond the intertidal zone. Limnetic Zone - The limnetic zone is the well-lit, open surface waters in a lake, away from the shore. The vegetation of the littoral zone surrounds this expanse of open water and it is above the profundal zone. Profundal Zone - The profundal zone is a deep zone of a body of water, such as an ocean or a lake, located below the range of effective light penetration. This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly. The lack of light in the profundal zone determines the type of biological community that can live in this region, which is distinctly different from the community in the overlying waters. The profundal zone is part of the aphotic zone
This depends on what zone you live in.
The Limnetic zone should have the most plankton, as it is the section with the best suitable conditions for organisms to thrive. The Limnetic zone is wide opened to sunlight, and is also oxygen filled. However the profundal zone has a very limmited supply of oxygen and sunlight, which makes the water cold and harder for organisms, such as plankton to thrive there.
well maybe because plants need light to grow...?
sunlight reaches the bottom
Waters as deep as 200 meters are referred to as the epipelagic zone, or the photic zone.The upper layer of a marine ecosystem is the limnectic zone, where sunlight penetrates. Below it are the profundal zone and the benthic zone.
weeds of course
This depends largely on which body of water we're talking about. The temperature of the photic zone in the arctic is definitely different that that of the tropics. What we can say is that due to the allowance of light, it is warmer than the aphotic (profundal) zone.
